Immiscible Fluid Mixture report

Use the Immiscible Fluid Mixture report type to generate the reports on mass, volume, and centroids data for each constituent of a fluid mixture.

The Summary table contains, at each sampling time and for each constituent:

  • Mass and volume sums over the flow domain.

  • Cumulative mass and volume inflow and outflow totals from the beginning of the run.

  • Constituent subdomain centers of mass, and total mass removed and redistributed by the mass redistribution algorithm.

The Centroids table contains, at each sampling time and for each constituent, the constituent subdomain centers of mass and overall flow domain center of mass.

The software reports on the entire model for each solution time step. In the tables, Time indicates the time step of a transient run. For a steady state solution, this column is equal to zero.

Example:

This example shows a partial report for a solution that includes an Immiscible Fluid Mixture type Report simulation objects named Immiscible Fluid Mixture Report. The tables display the data for only the first two time steps.
